Ok, I've been working on this for awhile now off and on. I havne't really been able to put all of my time in to it w/ school and other things coming up. Well I finally got a working model that has been tested completely.

What it is:
Two transistors. NPN and PNP. Now I honestly don't know what transistors do. I had to employ 100% help from a guy, Chkdsk, on www.the12volt.com's forums. This guy is awesome, drew me a schematic and everything.

What it does:
Now this is the cool part. A lot of you have seen Phil's interrior setup w/ LED's where he uses a relay and a Music Interface to create a cool effect.

McCook and I'm sure a few others have used this as well. Now the problem with this setup is a relay clicks any time it turns "on," so every time the music "hits," you get a click icon_sad.gif I tried sound dampening and everything and couldn't get it shut up. lol
This transistor setup is completely silent. They can handle up to 25amp, and from what I can tell, absolutely no draw back except the extra work involved.

I just wanted to share really. Don't know what else to say... but I'm happy it's done.

I'll make sure to post when I get to the next phase ;)

That's AWESOME, and it is so much LESS work than the relay setup I did. I actually ripped all that out in the summer so I don't have any interior neons. Heh..

But I never thought you could do that with transistors. Can you post the specific part numbers/links to the allelectronics page and maybe a diagram?

Good job. icon_lol.gif

And yes, of course I'll post the diagram etc. as well as links on where to get it all. I just don't have the time right now. But ya. biglaugh.gif

I'll post more in the morning -- I'm kind of tired and on my way to bed.
This will replace any standard SPDT relay (that's your standard 5 pin) and it's quiet. I was very lazy about actually testing it. I actually soldered it a long time back, and it worked, but I never fully tested it b/c it took too long to set up using a computer power supply.... but it works awesome -- Love it -- very silent.
Like I said, more details in the morning

send it to me, I'll test that puppy for you!

BTW does this guy know how to make LEDs strobe like the healights of the 'lade in the pictures/videos section????????? I may need to ask him.

Sorry to bring up this old ass thread, but Brandon, do you have any more information about this? I want to do something like this with the cathode music interface.

No, it doesn't strobe.

It switches two neons. Like, one will be on, but when the music interface activates, it switches that one off and turns a different one on. It's a neat effect.

bah, I'm embarrassed that I haven't finished this project yet. It's been over a year since I first soldered these together and they still aren't in my car.
The current hold up: SG 12" mini's not lighting up all the way (not even hooked up to the transistors), and I'm working 40 hrs a week now.

Sorry icon_redface.gif

those gifs aren't working. If I buy the relay what wires do I hook up with what. I mean what are the numbers on the relay to the wires. I am really interested in doing this I just need a diagram. Thanks again

Uhmmm I don't think you should use a relay. Clicking is bad

I also don't think you should do it until you buy a second color ;)

if you use a relay, it will click every time. It gets very annoying very fast.

Sorry, I didn't save the diagrams for the relay, I have to go to work soon. If I get time tonight I can redo them. I just have to dig out a relay to look at the pins.

Cool, I will have the relay somewhere where you can't hear it. I just want to do it and see what it looks like. Thanks again.
